Detailed Description

Standard Ignition TH348 is an emission control sensor used to report throttle angle to the vehicle control system. Accurate throttle position input is important for fuel delivery, idle quality, acceleration response, and drivability. This TH348 throttle position sensor is listed for 1999-2005 Porsche 911 and 1997-2004 Porsche Boxster applications, making it a focused replacement choice for Porsche owners servicing throttle signal faults. This part cross-references Bosch 0280122016 for the same application.

What It Helps Address

• Throttle signal errors that trigger drivability concerns
• Unstable idle caused by incorrect throttle input
• Delayed or inconsistent throttle response
• Check engine light conditions related to throttle position feedback
• Rough acceleration behavior tied to sensor wear

Installation Notes and Tips

Verify connector style, terminal layout, and sensor indexing before installation. The TH348 uses a female oval plug-in connector with male blade terminals, so the harness connection should match the original unit. Confirm application by year and model before ordering, especially on Porsche 911 and Porsche Boxster vehicles. No gasket is included.

Quality Assurance

Standard Ignition supplies replacement ignition and engine management components for service use. TH348 is built to match the listed fitment and connector configuration for the specified Porsche applications.
